115.xxx Warning [115.xxx] Invalid eddy loss measurement.
Reason:
Solution:
116.xxx Warning [116.xxx] Knee point too low! CTs with a knee point below 1 volt are not supported.
Reason:
Solution:
121.xxx Warning [121.xxx] Test not successful! Reverse polarity. Check wiring and repeat the
measurement.
Reason:
Solution:
130.xxx Warning [130.xxx] Burden impedance > 1kOhm.
Reason:
Solution:
131.xxx Warning [131.xxx] Overload during Burden measurement.
Reason:
Solution:
140.xxx Warning [140.xxx] Timeout during remanence test. Measured magnetic flux is unstable. Reduce
noise level.
Reason:
Solution:
200.xxx Warning [200.xxx] Check connection. Make sure burden is properly wired.
Reason:
Solution:
200.xxx Warning [200.xxx] Check CT SB2 switch box wiring: CTA OUTPUT and/or BURDEN terminal may
be disconnected.
Reason:
Solution:
201.xxx Warning [201.xxx] Check connection. Measured ratio > 50000:1.
Reason:
Solution:
202.xxx Warning [202.xxx] Check connection. Polarity of input SEC and power output are not the same.
Reason:
Solution:
203.xxx Warning [203.xxx] Check connection. Input SEC may be disconnected.
Reason:
Solution:
204.xxx Warning [204.xxx] Check connection. Polarity of input PRIM and power output are not the same.
Reason:
Solution:

Reliable determination of the eddy losses is not possible.
Verify the wiring and repeat the test. If the error message is displayed repeatedly, it is
currently not possible to test this CT using the CT Analyzer.
The knee point voltage is smaller than 1 V.
Currently it is not possible to test CTs with such a low knee point using the CT Analyzer.
Measured polarity is wrong.
Reverse the polarity of the measurement cables on the primary or secondary side of the
CT.
Burden impedance > 1kΩ.
The test cannot be continued. Check the connections to the Burden.
The required test current cannot be reached, even at the maximum output voltage.
The CT Analyzer cannot deliver enough current. Reduce the test current or the impedance
of the burden. Check the wiring for proper contacts; one connection possibly has a bad
connection.
The magnetic flux during remanence measurement is not stable.
The test cannot be continued. Check the connections to the CT. Try to reduce the noise
level for the measurement.
The measured input voltage differs by more than 5V from the input voltage expected during
burden test.
Check whether the output generator ("Output") and measurement input "Sec" are
connected correctly.
The measured input voltage differs by more than 5V from the input voltage expected during
the burden test using the CT SB2 switch box.
Check whether the BURDEN OUT and the BURDEN IN sockets on the CT SB2 are
connected correctly.
Measurement input "Prim" is possibly not connected properly.
Check whether the primary side measurement input "Prim" is connected properly.
Polarity of input "Sec" and "Output" are not the same.
Check whether the output generator ("Output") and measurement input "Sec" are
connected properly and with correct polarity.
Input signal at input "Sec" differs from the expected one.
Check whether the output generator ("Output") and measurement input "Sec" are
connected properly.
Input signal at input "Prim" differs from the expected one: Reverse polarity at input "Prim".
Check whether the output generator ("Output") and measurement input "Prim" are
connected properly and with correct polarity.
